AB The growth of the world’s energy demand over recent decades in relation to energy intensityand demography is clear. At the same time, the use of renewable energy sources is pursued toaddress decarbonization targets, but the stochasticity of renewable energy systems produces anincreasing need for management systems to supply such energy volume while guaranteeing, at thesame time, the security and reliability of the microgrids. Locally distributed energy storage systems(ESS) may provide the capacity to temporarily decouple production and demand. In this sense,the most implemented ESS in local energy districts are small–medium-scale electrochemical batteries.However, hydrogen systems are viable for storing larger energy quantities thanks to its intrinsic highmass-energy density. To match generation, demand and storage, energy management systems (EMSs)become crucial. This paper compares two strategies for an energy management system based onhydrogen-priority vs. battery-priority for the operation of a hybrid renewable microgrid. The overallperformance of the two mentioned strategies is compared in the long-term operation via a set ofevaluation parameters defined by the unmet load, storage efficiency, operating hours and cumulativeenergy. The results show that the hydrogen-priority strategy allows the microgrid to be led towardsisland operation because it saves a higher amount of energy, while the battery-priority strategyreduces the energy efficiency in the storage round trip. The main contribution of this work lies in thedemonstration that conventional EMS for microgrids’ operation based on battery-priority strategyshould turn into hydrogen-priority to keep the reliability and independence of the microgrid in thelong-term operation.
